Dítě D., Šoltés R. & Jasík M.: Opätovne potvrdený výskyt Meesia triquetra v Národnom parku Nízke Tatry v kontexte výskytu druhu na Slovensku, 1–5Rediscovery of Meesia triquetra in the National Park Nízke Tatry Mts in the context of its occurrence in SlovakiaAbstract: In Central Europe, Meesia triquetra is considered as glacial relic species. In Slovakia, this moss species rarely grows in fens in the northern part of the country, especially in the Orava and Tatry regions. Only historical, long-time unconfirmed localities are related to the Nízke Tatry Mts. In 2010, the occurence of Meesia triquetra in the Nízke Tatry Mts was confirmed in two localities, near the villages of Liptovská Lúžna and Vikartovce.

Váňa J.: Přínos botaniků 19. století narozených a působících na českém území k nomenklatuře a taxonomii mechorostů. I. Philipp [Filip] Maximilian Opiz, 5–18Contribution of botanists of 19th century born and working in the area of present Czech Republic to the nomenclature and taxonomy of bryophytes. I. Philipp [Filip] Maximilian OpizAbstract: The contribution to the taxonomy and nomenclature of bryophytes made by the botanists of 19th century born and working in Bohemia and/or Moravia will be summarized in some articles. The first one is devoted to Philipp [Filip] Maximilian Opiz, one of the most important Czech botanists of this epoche. Short biography, his contribution to bryology, information about his herbarium and publications with bryological data are presented. The core of the article creates the list of taxa of bryophytes published or only named (in sched.) by Opiz; valid taxa are in boldface. Complete bibliographic references and the information about the revision and present categorisation of these taxa are given.

Šoun J.: První nález Calicium montanum v České republice, 19–23First record of Calicium montanum from the Czech RepublicAbstract: Recently described lichen species Calicium montanum is recorded for the first time from the Czech Republic. It was found in a relict pine forest in the Vltava river valley, at the margin of the Protected Landscape Area (PLA) Blanský les in South Bohemia. Description, ecology and distribution of the species are shortly presented. Accompanying lichen species are listed and lichen bibliography of PLA Blanský les is reviewed.

Štechová T., Manukjanová A., Holá E., Kubešová S., Novotný I. & Zmrhalová M.: Současný stav populací druhů Helodium blandowii (Thuidiaceae) a Scorpidium scorpioides (Calliergonaceae) v České republice, 24–33The present state of Helodium blandowii (Thuidiaceae) and Scorpidium scorpioides (Calliergonaceae) populations in the Czech RepublicAbstract: Populations of two endangered moss species Helodium blandowii and Scorpidium scorpioides were investigated in all recently known localities in the Czech Republic. At each locality, population size, basic water chemistry and vegetation characteristics were recorded. Recently, H. blandowii occurs at five localities – fen meadows and moderately rich fen. Its populations but one are rather small. S. scorpioides grows in seven sites – rich or calcareous rich fens and inundated sand pit and its populations are rather large.

Plášek V., Popelářová M. & Kubešová S.: Mech Pseudobryum cinclidioides (Huebener) T. J. Kop. v Moravskoslezských Beskydech v kontextu recentních údajů z ČR a SR, 34–37The moss Pseudobryum cinclidioides (Huebener) T. J. Kop in Moravskoslezské Beskydy Mts in the context of its recent records in the Czech Republic and SlovakiaAbstract: The paper presents a new locality of endangered moss species in the valley of the Černá Ostravice stream in Moravskoslezské Beskydy Mts. In addition, recent records of this species in Czech Republic and Slovakia are given.

Koval Š. & Zmrhalová M.: Znovunalezení hlevíků Anthoceros neesii a Notothylas orbicularis v České republice, 38–46Rediscovery of hornworts Anthoceros neesii and Notothylas orbicularis (Anthocerotophyta) in the Czech RepublicAbstract: The occurrence of Anthoceros neesii Prosk. and Notothylas orbicularis (Schwein.) A. Gray in the Czech Republic was confirmed after 90 years. We rediscovered them at four stubble-fields in the Hrubý Jeseník Mts foothills. Only 7 individuals of Notothylas orbicularis were found at four sites, whereas Anthoceros neesii occurred together with the previous species at only three sites, however in a much bigger abundance. Rapid changes in agricultural management cause gradual disappearing of fields, which represent suitable habitats for hornworts, from submontane region of the Czech Republic. Consequently, both species could eventually vanish from our region in the future.

Němec R. & Musil Z.: Mechorosty polních mokřadů Znojemska – první přiblížení, 46–50Bryophytes of the agricultural field wetlands in the Znojmo region – preliminary resultsAbstract: This paper shows first bryofloristical data of the agricultural field wetlands in the Znojmo region (the Czech Republic, south-western Moravia). The old maps and ortophotos were used to recognize wetlands in the landscape and the samples were collected from the detected localities. Liverwort Riccia cavernosa and moss Physcomitrella patens, both being rare in the Czech Republic, were recorded.

Uhereková-Šmelková D. & Mišíková K.: Stručný prehľad machorastov vybraných hradov a zrúcanín na Slovensku, 51–55A short overview of bryophytes of selected castles and castle ruins in SlovakiaAbstract: Altogether 41 epilithic bryophyte species were recorded from 20 Slovak castles and castle ruins. The prevailing habitats are dry substrates of calcareous stones, walls, daub, sporadically basalt or brick. In average 13 species were recorded on each site, the most common mosses were Tortula muralis, Anomodon viticulosus, Bryoerythrophyllum recurvirostrum and Homalothecium sericeum.

Malíček J., Palice Z., Kocourková J. & Müller A.: Příspěvek k poznání flóry lišejníků CHKO Beskydy, 56–66Contribution to the lichen flora of the Beskydy Protected Landscape AreaAbstract: The list of 174 lichens and 5 lichenicolous fungi recorded in the Beskydy Protected Landscape Area (Eastern Moravia, Czech Republic) is presented. Numerous small-scaled areas of old-growth forests occur in the study area, but current lichenofloristic data are nearly absent from this region. We have not confirmed most of the susceptible old-growth forest species that were reported by earlier authors during last century. Bacidina phacodes, Gyalecta flotowii, Multiclavula mucida, Parmelia submontana, Pertusaria hemisphaerica and Trapelia corticola represent the more valuable epiphytic lichens in primeval forests. Other rare, overlooked or poorly known lichens are dealt in more detail (e.g. Bilimbia microcarpa, Micarea byssacea, M. nigella, Porina guentheri, Thelocarpon olivaceum). Additional records from the Czech Republic are listed for Bilimbia microcarpa, Multiclavula mucida, Thelocarpon olivaceum and Trapelia corticola. The sorediate species Caloplaca turkuensis is reported as a new species for the Czech Republic. According to our observations the most interesting lichen flora is developed in old-growth forest stands, deep brook valleys, and on solitary trees or alleys. The peaks of mountains are generally characterized by poorly developed acidophilous lichen assemblages.

Dítě D. & Šoltés R.: Rozšírenie druhu Scorpidium scorpioides na Slovensku: minulosť a súčasnosť, 66–69Distribution of Scorpidium scorpioides in Slovakia: past and presentAbstract: In Central Europe, the moss Scorpidium scorpioides is considered as glacial relict species. In Slovakia, it was known only in a single locality in the Kubínska hoľa Mt., where it was discovered in 1998. In 2009, we confirmed an unpublished historical record of vegetation scientist Kamil Rybníček in another fen in the same mountain range – the saddle mire below the Minčol Mt. The population is not abundant, covering an area of one square meter.
